COMBINED STEAM AND WATER VALVE. I

SPEGIFICATIQN forming part of Letters Patent No. 753,427,

Application filed August 26, 1902.

T0 at whom it may concern: 7

Be it known that we, LEWIS A. PARKER and HARRISON D. OASTLEBEBY,citizens of the United States, residing at Leavenworth, in the county ofChelan and State of Washington, have invented and produced a new anduseful Combined Automatic Steam and Water Valve, of which the followingis a specification.

Our invention relates to an improvement in quick-acting valves.

The object of the invention resides in providing means forsimultaneously opening the water and steam valves and in means forantomatically returning the valves to their seats.

Another object of the invention is to provide a device of the characterdescribed which willbe strong, durable, and efilcient and one in whichthe parts will not be liable to get out of working order.

With the above and other objects in view the invention consists in thenovel details of construction and operation described in thespecification and illustrated in the drawings, wherein Figure 1 is anelevation of the valves. Fig. 2 is an end elevation of the valves, Fig.3 is a vertical section of the valves, and Fig. 4: is a transversesectional view taken on the line y y of Fig. l.

In the drawings, A designates the watervalve casing, and B thesteam-valve casing,

which are connected by an integral web I. The casings A and B areprovided with screwthreaded openings to receive the supply-pipes andformed with valve-chambers A and B, having valve-seats in their lowerends. Valves D, opening and closing against the said seats, are providedwith stems C, which extend through the bottom of the casing, wherepacking-nuts E are located, and are provided on their ends with bossesGr, which latter are held in place by pins 72,. Springs F encircle thevalve-stems C and are confined between the packing-nuts E and the bossesfor the purpose of holding the valves D upon their seats.

The water-valve casing A is formed with a screw-threaded neck 0, intowhich is fitted a coupling 0, having secured to its outer end a T m. Anipple L, having one end internally dated March 1, 1904.

Serial No. 121,144.. (No model.)

and externally threaded, is screwed into the T, carrying the jet-nozzleP, at one end and screwed into an elbow is at its other end. The

elbow is is coupled to the steam-valve casing by a coupling J.

N designates the outlet through which the water and steam pass.

The hanger U, secured to the web I by bolts TV, supports the shaft V, towhich are fastened arms T, which bear againstthe bottoms of the bossesGr. An operating-lever S is also supported upon the shaft and projectsin an opposite direction to the arms T.

From the foregoing it will be readily seen that the ports Q and B beingconnected with sources of water and steam supply, respectively, thevalve-chambers A and B are filled with fluid. A downward pressure beingap' plied to the lever S, the shaft V is rocked, causing the arms T,bearing against the bosses Gr, to raise the valve-stems 0 against thetension of the spring F and lift the valves D, thus allowing the fluidsto pass from the chambers A and B into the valve-casings. The

steam passing through the coupling J and out of the nozzle 1? by way ofthe elbow is and the nipple L creates a vacuum, drawing the water fromthe valve-casing A through the coupling 0 into the T m, where both thesteam and water pass out through the outlet M. Pressure upon lever Sbeing relieved, the valves are returned to their seats through themedium of the springs F, which, as before stated,- were compressed uponthe opening of the valve.

W'e do not wish tolimit our invention to the exact details ofconstruction and operation herein set forth, as we may make variouschanges in the same without departing from the spirit of our invention.

Having thus fully described our invention, what we claimas new,'anddesire to secure by Letters Patent, is-

1. In a device of the character described, the combination with awater-valve and a steamvalve, stems projecting from the valves, of meansfor simultaneously operating the valves comprising, a rock-shaft,projections from the shaft engaging the stems, a lever for rocking theshaft to open the valves, and resilient means carried by the stems forclosing the valves, substantially as described.

2. In a device of the character described, the combination with avalve-casing, of a steamvalve and a water-valve operating therein, stemsdepending from the valves, springs confined on the lower end of thestems, arms supported from the casing and bearing against the ends ofthe valve-stems, a pivoted lever connected to the arms, and a jet-nozzleconnected to the valve-casing, substantially as described.

3. In a device of the character described, the combination with avalve-casing, of a steamvalve and a water-valve operating therein, stemsdepending from the valves carrying
